The Extended Access Log Valve is a variant of + the Access Log Valve. It is not a real extension of the standard + Access Log valve, instead it supports the so-called + Extended Log File Format + defined by the W3C. The main difference to the standard + AccessLogValve are the supported pattern values.

+ + + + + +

The Extended Access Log Valve supports the following + configuration attributes:

+ + + + +

Java class name of the implementation to use. This MUST be set to + org.apache.catalina.valves.ExtendedAccessLogValve to + use the extended access log valve.

+ + + +

Absolute or relative pathname of a directory in which log files + created by this valve will be placed. If a relative path is + specified, it is interpreted as relative to $CATALINA_BASE. If + no directory attribute is specified, the default value is "logs" + (relative to $CATALINA_BASE).

+ + + +

Character set used to write the log file. An empty string means + to use the system default character set. Default value: use the + system default character set. +

+ + + +

A formatting layout identifying the various information fields + from the request and response to be logged. + See below for more information on configuring this attribute.

+ + + +

The prefix added to the start of each log file's name. If not + specified, the default value is "access_log.". To specify no prefix, + use a zero-length string.

+ + + +

Set to true to check for the existance of request + attributes (typically set by the RemoteIpValve and similar) that should + be used to override the values returned by the request for remote + address, remote host, server port and protocol. If the attributes are + not set, or this attribute is set to false then the values + from the request will be used. If not set, the default value of + false will be used.

+ + + +

Set to true to convert the IP address of the remote + host into the corresponding host name via a DNS lookup. Set to + false to skip this lookup, and report the remote IP + address instead.

+ + + +

The suffix added to the end of each log file's name. If not + specified, the default value is "". To specify no suffix, + use a zero-length string.

+ + + +

Flag to determine if log rotation should occur. + If set to false, then this file is never rotated and + fileDateFormat is ignored. Use with caution! + Default value: true +

+ + + +

Turns on conditional logging. If set, requests will be + logged only if ServletRequest.getAttribute() is + null. For example, if this value is set to + junk, then a particular request will only be logged + if ServletRequest.getAttribute("junk") == null. + The use of Filters is an easy way to set/unset the attribute + in the ServletRequest on many different requests. +

+ + + +

Allows a customized date format in the access log file name. + The date format also decides how often the file is rotated. + If you wish to rotate every hour, then set this value + to: yyyy-MM-dd.HH. The default value is + yyyy-MM-dd. The date format will always be localized + using the locale en_US. +

+ + + +

Flag to determine if logging will be buffered. + If set to false, then access logging will be written after each + request. Default value: true +

+ + + + +

Values for the pattern attribute are made up of + format tokens. Some of the tokens need an additional prefix. Possible + prefixes are c for "client", s for "server", + cs for "client to server", sc for + "server to client" or x for "application specific". + Furthermore some tokens are completed by an additional selector. + See the W3C specification + for more information about the format.

+ +

The following format tokens are supported:

+
    +
  • bytes - Bytes sent, excluding HTTP headers, or '-' if zero
    • +
  • c-dns - Remote host name
    • +
  • c-ip - Remote IP address
    • +
  • cs-method - Request method (GET, POST, etc.)
    • +
  • cs-uri - Request URI
    • +
  • cs-uri-query - Query string (prepended with a '?' if it exists)
    • +
  • cs-uri-stem - Requested URL path
    • +
  • date - The date in yyyy-mm-dd format for GMT
    • +
  • s-dns - Local host name
    • +
  • s-ip - Local IP address
    • +
  • sc-status - HTTP status code of the response
    • +
  • time - Time the request was served in HH:mm:ss format for GMT
    • +
  • time-taken - Time (in seconds as floating point) taken to serve the request
    • +
+ +

For any of the x-H(XXX) the following method will be called from the + HttpServletRequestObject:

+
    +
  • x-H(authType): getAuthType
    • +
  • x-H(characterEncoding): getCharacterEncoding
    • +
  • x-H(contentLength): getContentLength
    • +
  • x-H(locale): getLocale
    • +
  • x-H(protocol): getProtocol
    • +
  • x-H(remoteUser): getRemoteUser
    • +
  • x-H(requestedSessionId): getGequestedSessionId
    • +
  • x-H(requestedSessionIdFromCookie): + isRequestedSessionIdFromCookie
    • +
  • x-H(requestedSessionIdValid): + isRequestedSessionIdValid
    • +
  • x-H(scheme): getScheme
    • +
  • x-H(secure): isSecure
    • +
+ +

+ There is also support to write information about headers + cookies, context, request or session attributes and request + parameters. +

+
    +
  • cs(XXX) for incoming request headers with name XXX
    • +
  • sc(XXX) for outgoing response headers with name XXX
    • +
  • x-A(XXX) for the servlet context attribute with name XXX
    • +
  • x-C(XXX) for the first cookie with name XXX
    • +
  • x-O(XXX) for a concatenation of all outgoing response headers with name XXX
    • +
  • x-P(XXX) for the URL encoded request parameter with name XXX
    • +
  • x-R(XXX) for the request attribute with name XXX
    • +
  • x-S(XXX) for the session attribute with name XXX
